Researchers found that an inactive subduction zone under the Strait of Gibraltar may begin migrating into the Atlantic Ocean, commencing the shrinking process. The zone also brings a higher risk ...

Not all mountains in the Yellowstone region are volcanic in origin. The Wind River Range, southeast of Yellowstone National ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

An earlier study showed that a large subduction zone must have run through the western paleo-Pacific Ocean, which separated the known Pacific plates in the east from a hypothetical Pontus plate in ...

What happens, then, to keep the Earth the same size? The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary ...

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

High-Resolution Anisotropic Tomography Reveals Mantle Flow Complexity and Slab-Plume Interactions, Redefining Subduction Zone ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.

This earthquake is larger than much of the recent seismic activity around western Washington, per initial reports.
